Those who do not check if they are communicating with AI could often find themselves in a situation where their posts are deleted as a result of the entire thread being deleted.
I don't check whether a topic is created by AI but by glance at it, if I feel it is a zero-value, plagiarism, AI, just possibly in my thinking, I will skip it. Like you shared, such threads have high probability to be trashed.
It's not about my posts will be trashed together with that thread, but basically it is time wasting to reply in a zero-valued topic.
Using face validity to check AI-generated content might be highly deceptive. I read that one of the ways of identifying them is that they usually have no grammatical or spelling errors. But with the popularity of Grammer checking tools like Grammerly which help writers to produce close-to-perfect writing, this method of identifying these AI writing will not work. As Lucius rightly pointed out, the best option is to check these suspected posts in more than one detecting software.to check its authenticity.
